In Splunk Enterprise versions below 9.4.3, 9.3.5, 9.2.7, and 9.1.10, and Splunk Cloud Platform versions below 9.3.2411.104, 9.3.2408.113, and 9.2.2406.119, an unauthenticated attacker could send a specially-crafted SPL search command that could trigger a rolling restart in the Search Head Cluster through a Cross-Site Request Forgery (CSRF), potentially leading to a denial of service (DoS).The vulnerability requires the attacker to phish the administrator-level victim by tricking them into initiating a request within their browser. The attacker should not be able to exploit the vulnerability at will.See How rolling restart works for more information.
The web application does not, or can not, sufficiently verify whether a well-formed, valid, consistent request was intentionally provided by the user who submitted the request.
